Implementation Of A Virtual Synchronous Machine To Improve The Dynamic Response Of Inverters

This paper proposes a control technique that allows inverters to work as if they were synchronous machines, assuming the characteristics and properties that these machines have. The development of each control block that composes the Virtual Synchronous Machine (VSM) is presented. The proposed VSM can operate isolated, in parallel with other VSM's, sharing the active and reactive demanded power and connected to the main grid, without the need of control switching between grid-connected and isolated modes. Simulated and experimental results prove the developed theory.
